STAPLING DEVICE Filed Jun 2o, 1929 BY Max VUEEL Patented Dec. 15, '1931 UNITED STATESl PATENT OFFICE MAX VOGEL, OF FRANKFOBT-ON-THE-MAIN, GERMANY, ASSIGNOR T NEVA-CLOG PROD- UCTS, INC., OF BBIDGEPORT, CONNECTICUT, A CORPORATION. OF CONNEGTICU T STAPLING DEVICE Application led June 20,

The present invention relates to an 'zmproved stapling device, particularly of the plier type, and has for an object to provide a construction which will so insert and clinch the staples that the clinched over ends will be in substantially flat parallel relation against the stapled material, thus obviating theobjrectionable characteristics of stapling devices heretofore known, with which the ends of the staples were so bent that they were curved and projected from `the surface of the stapled material.

Another object is to provide a staplingdevice of this character which will grip the material to be stapled before the staple is driven therethrough.

Other objectsare to provide a stapling device of simple construction, and which .will be reliable and efficient in use.

With the above and other objects in view, an embodiment of the invention is shown in the accompanying drawings, and this embodiment will be hereinafter more fully described with reference thereto, and the invention will be finally pointed out in the claims.

disposed within the. side portions 12,

ber 10. The side portions 12, 13 are provided` with forwardly projecting arm portions 19, 20 adapted, as will presently n'ore fully appear, to support the lower jaw parts of the evice.

The staple casing-21 is of known construction, as shown for instance in my lPatent #1,043,883 of November 12, 1912; being pivotally mounted upon the pin 16, as at 22, and rovided at its forward end with a vert-ical y arranged guide slot 23, in which the staple driver 24 moves.

. A transverse Spanner block 25 is rigidly secured between the ends of the arms 17,

18, and supports a bolt 26 having its end slidably engaged in an aperture 27 in the upper end of the staple driver, the end of said bolt being screw-threaded for the provision of a nut 28, against which the driver 24 is pressed by means yof a spring 29, ar'- ranged between the block 25 and the driver.

Between the arms 19, 2O there is rigidly,

supported an anvil member consisting of a base portion '30, upwardly extending side portions 31, 32, engaged between said arm 19, 20, and secured thereto by a transverse 'pin 33 and set-screws 34, 35 4at each side, and an upwardly extending'forward end portion 36, provided at its upper edge with an anvil portion 37, having its ends spaced 'inwardly from the sideportion 31, 32, and provided in its upper surface with a concave groove 38. A spring 39 is connected between a hook 40 formed on the handle 11 and a hook 41 on the base of the anvil member, and tends to keep the jaws of the device open. x

A cheek member is movably and cooperatively supported above the anvil member and consists-of a flat top portion 42, of reduced width at its inner portion and provided at each edge of said reduced portion with downwardly extending ears 43, 44, disposed within the side portions 31, 32 of the anvil member and pivotally mounted on the pin 33. At each side of the forward end of the top portion 42 therel are providedA downwardly extending flanges 45, 46 disposed outwardly of the anvil member, and at the forward end a` cammin abutment portion 47 isA curved downward y and inwardly and then upwardly toward the forward end of the anvil. A slot 48 is formed in the upper portion 42 in registering relation with the anvil, so that upon relative movement of the cheek member towardthe anvil the latter may move into said slot. The ends of the slot are beveled, as at 49, 5l),` to direct the ends of the staples inwardly, as will presently more fully apear. p The relative position of the cheek member is controlled by means of a slide rod 51, having an eyelet 52 at its inner end pivotally mounted upon a stud 53 secured to the side portion 14 of wthe handle member 11, and extending at its forward end through an aperture 54 in the forward end portion 36 of the anvil member, where .it engages beneath the camming abutment 47. The forward end of the rod is beveled, as at 55, for cooperation with the inwardly extending camming portion of said abutment to permit Ythe eek member to move toward the anvil member as the rod is drawn inwardly through closing of the jaws. 4

In operation the papers to be fastened together, as documents or the-like, are placedA between the jaws of the device, whereupon by actuating the handles said papers are firmly gripped by the jaw. Continued movemerit of the handles causes the stapledriver 24 todescend in its guide-slot, pushing the staplethrough the material. The points of the staple thereupon engage the beveled ends 49, of the slot 48 so that they bend toward each other, being guided 'as they leave said/beveled ends by engagement inthe curved groove of the anvil. Up to this point the cheek member is supported bythe rod 51 in its raised position with respect to the anvil, and as indicated in Figs. 2 to 6. Als the handles are further drawn together the rod 51 is drawn inwardly to a point where the beveled end 54 engages the inwardly extending camming surface of the camming abutment 47, where-I upon the anvil member moves upwardly toward the check member, clinching the staple ends upon the under side of the material, and finally as the anvil portion 87 moves completely into the slot 48, as shown in Figs. 7 and 8, pressing said staple ends in tight fiat relation against the under side of the stapled papers. In releasing the pressure upon the handles the springs 29 and 39 will bring the device into its initial position, in which the material can be drawn from the jaw, the rod 51 I claim and desire to secure by Letters Patent being projected during this operation to raise the cheek member to its normal spaced relation above the anvil.
